Display controller installation
Medical Imaging Display Systems product line. The PCIe versions of
these boards will have the same features as the currently shipping PCI
version.
All three PCIe boards will feature a x8 logical bus on a x8 physical
connector. They have been designed to function in PCI Express x8 or x16
slots. Optimum performance will always be obtained by installing them
in a PCIe x8 slot. Depending on your PC manufacturer's implementation
of the logic for the PCIe x16 slot optimum performance may also be
obtained by installing the Barco PCIe boards in the PCIe x16 slot.
Connecting your Barco displays to your BarcoMed PCIe board is identical
to connecting them to a BarcoMed PCI board (please refer to your
system manual for details).
